The deadline of 31st January 2024 for submitting Self Assessment tax returns for the 2022/23 tax year is looming. If you need to submit a tax return, it is important to do so by the deadline to avoid paying late filing penalties.

You can check whether or not you need to complete a tax return for 2022/23 by using the government tool.

If you submit your return later than the deadline, you will typically face a £100 penalty if the tax return is up to 3 months late. Should the return be submitted over 3 months late, you may be faced with a larger penalty.

Any payment for underpaid tax must also be received by HMRC by 31st January 2024. You will be charged interest by HMRC on any late tax payments:

• 30+ days late – you’ll need to pay a 5% penalty of the tax owed
• 6+ months late – you’ll need to pay a further 5% penalty of the tax owed
• 12+ months late – you’ll need to pay an additional 5% penalty of the tax owed
